Suggested solutions
If a vertical white streak or faded area appears on the page:
• The toner supply is low. You may be able to temporarily extend the toner cartridge life.
See "Redistributing Toner". If this does not improve the print quality, install a new toner
cartridge.
• The paper may not meet paper specifications; for example, the paper is too moist or too
rough. See "Paper Specifications".
• A combination of faded or smeared defects may indicate that the toner cartridge needs
cleaning. See "Cleaning the Interior".
• The surface of the LSU part inside the printer may be dirty. Clean the LSU (see
"Cleaning the Interior").
• The paper may not meet specifications; for example, the paper is too moist or too rough.
See "Paper Specifications".
• The transfer roller may be dirty. Clean the inside of your printer. See "Cleaning the
Interior".
• The paper path may need cleaning. See "Cleaning the Drum".
If faded areas, generally rounded, occur randomly on the page:
• A single sheet of paper may be defective. Try reprinting the job.
• The moisture content of the paper is uneven or the paper has moist spots on its surface.
Try a different brand of paper. See "Paper Specifications".
• The paper lot is bad. The manufacturing process can cause some areas to reject toner. Try
a different kind or brand of paper.
• The toner cartridge may be defective. "Vertical repetitive defects" on the next page.
• If these steps do not correct the problems, contact a service representative.
